Description
Summary:A GIS-based study was initiated in Mewat region, District Gurgaon, Haryana, an integral part of traditionally known malaria epidemic belt of the Northwestern Plains of India. The study included (i) delineation of malaria paradigms at macro level; (ii) identification of eco-epidemiological characteristics of each paradigm, and (iii) identification of the paradigm receptivity for malaria. Using RS and GIS, the five easily recognizable malaria paradigms, namely irrigation command, catchment/non-catchment, mining, urban and flood-prone areas, were mapped. Each paradigm exhibited its own eco-epidemiological characteristics and potential for maintaining malaria transmission of varying intensity. Paradigm-wise receptivity revealed that during 1996, an epidemic year, different paradigms responded differently. Although all paradigms showed upward trend, maximum amplification occurred in urban/semi-urban paradigms. During 1993 and 1998, i.e. in the last two inter-epidemic periods, flood-prone paradigm, irrigation command area II and non-catchment area continued to retain active pockets of malaria, namely Akera and Malab sections in Nuh block; Uleta and Kankar Kheri in Nagina block; Biwan in Ferozpur Jhirka block; Punhana, Hathan gaon, Sunhera and Tirwara in Punhana block. With the current inter-epidemic period starting from 1998 onwards, any ecological change in the scenario influencing the above three paradigms favourably, may flare up malaria cases from hot pockets. Therefore there is a need to strengthen surveillance in these areas and pay special attention to these pockets.
